652 NEW SPECIES OF BRACONID^E. 



and posterior femora above toward apex, and the upper surface of tibiae, 

 more or less dusky; middle of abdomen reddish, shading into pieeous 

 black posteriorly, the 2d segment having a large yellow blotch on the 

 disk. 



The oblong head is a little longer than wide, with a distinct grooved 

 line extending from ocelli back to occiput ; the antenna? are long and 

 slender, more than 30-jointed (the tips are broken and exact number 

 can not be stated), the 1st joint of the tiagellum is the longest, about 

 four times as long as wide, the three following about thrice, and the 

 others twice as long as wide. The mesothoracic parapsidal grooves are 

 only indicated anteriorly, but just in front of the scutellum is a row of 

 coarse punctures, evidently the posterior portion of the grooves ; the 

 scutellum has a deep transverse fovea at base, the bottom of which shows 

 some delicate raised lines ; the margins of the mesopleura are punctured, 

 the sutures punctulate, the disk smooth but with a longitudinal grooved 

 line a little below the middle; metathorax rugose with indications of a 

 medial carina basal ly ; abdomen long, linear, much longer than the head 

 and thorax together, depressed or compressed from above and below ; 

 the petiole is black, as long as the trochanters and femora combined, 

 minutely rugose, the spiracles placed much before the middle. Wings 

 cinereous hyaline; veins dark brown. 



Habitat. — Garland, Colorado. 



Described from a single specimen collected by Mr. E. A. Schwarz. 



This species is the largest form yet discovered in our fauna, and can 

 not be confounded with any other. 



Subfamily MACRO CENTRING.

 Zele terminalis n. sp. 



Male. — Length, 4A mm . Head, thorax, and terminal segments of abdo- 

 men, black; metathorax brown; palpi and legs, pale yellow-ferrugi- 

 nous; antenna? black, covered with white hairs; two basal antennal 

 joints and basal two-thirds of 1st joint of tiagellum, yellow; the 1st 

 joint of the tiagellum is about eight times as long as thick, the others 

 subequal (tips are broken off, but there are 34 joints remaining). The 

 head and thorax are smooth, polished ; collar yellow above and at 

 sides, beneath black; parapsidal grooves distinct; mesopleura with a 

 large, oval fovea just beneath the wing, and a broad, longitudinal sul- 

 cus below the middle posteriorly, its surface being minutely wrinkled ; 

 metathorax coarsely rugose, a little longer than wide; abdomen linear, 

 longer than the head and thorax; the first three segments yellow-fer- 

 ruginous, and delicately longitudinally aciculated, the following seg- 

 ments smooth, black, and polished. Wings hyaline, iridescent; veins
